Abstract
A portable rechargeable personal ionic air purifier energizing a personal airspace and cleaning particulate pollutants therefrom in a manner that poses little or no personal shock risk and that minimizes battery drain to maximize battery life includes ionization means and ionization actuation means cooperative to provide ion bursts at regular intervals to energize and to clean particulates from the personal airspace. The ionization means includes an ion emitter and the ionization activation means includes means for providing a pulse train of predetermined frequency and duty cycle. The ion emitter may be removably mounted to a portable housing and/or to a facemask or other objects in the personal airspace via an elongated flexible cable.
